Overview
Moving from Fat Free CRM to Monday.com CRM is a structural migration from a self-hosted Rails database into a SaaS board-based CRM. Fat Free CRM has no documented REST API, so we connect read-only to its underlying MySQL, PostgreSQL, or SQLite database to extract relational data intact, including join tables for account-contact, opportunity-contact, and campaign-contact associations. Monday.com CRM uses a board-based architecture where CRM objects (Contacts, Companies, Deals, Leads) live as Items on custom Boards with typed Columns rather than as native CRM objects with fixed schemas. We create those Boards and Columns before migration, preserve link-table relationships using Monday.com Item connections or a reference board, and migrate custom fields as custom Column types. Attachments live on the Fat Free CRM filesystem and do not migrate automatically; we enumerate every attachment reference and deliver a file inventory for manual copy. Fat Free CRM user and group IDs have no meaning in Monday.com, so we export a user roster and the customer's admin creates Monday.com team members and reassigns ownership post-migration. Workflows, plugins, and automation configurations do not migrate; we deliver a written map for the admin to rebuild them as Monday.com Automations.

Object mapping
Each row shows how a Fat Free CRM object lands in monday CRM, including any object-level transformations, lookup resolution, or schema-design dependencies.
Typical mapping — final map is confirmed during the sample migration step.
Fat Free CRM
Account
monday CRM
Company Board / Item
1:1Fat Free CRM Accounts map to Items on a Companies Board in Monday.com CRM. We extract name, website, phone, billing address, and assigned user from the accounts table, then create Items with corresponding Column values. Account-Contact associations from the contact_accounts join table migrate as Monday.com Item Connections or a reference Items Board, depending on the customer's preferred relationship structure.
Fat Free CRM
Contact
monday CRM
People Board / Item
1:1Fat Free CRM Contacts map to Items on a People Board. Standard fields (first name, last name, email, phone, title) map to typed Columns. The contact_accounts join table links each Contact Item to its corresponding Company Item via Monday.com Item Connections. We resolve the Account reference before inserting Contacts to satisfy the relationship at migration time.
Fat Free CRM
Lead
monday CRM
Leads Board / Item
1:1Fat Free CRM Leads are distinct from Contacts with status, source, rating, and assigned user fields. We map them to a Leads Board in Monday.com with Columns for status, lead source, rating, and any custom fields. Lead-Account associations migrate as Item Connections. The customer's admin decides whether to merge Lead Items into the People Board post-migration or maintain a separate Leads Board.
Fat Free CRM
Opportunity
monday CRM
Deals Board / Item
1:1Fat Free CRM Opportunities link to an Account, track stage, amount, probability, and close date, and have an opportunity_contacts join table. We create a Deals Board with Columns for deal name, stage (mapped from Fat Free CRM stage values to Monday.com Status Column), amount, probability, and close date. The opportunity_contacts join table maps to Item Connections linking each Deal Item to the relevant Contact Items.
Fat Free CRM
Task
monday CRM
Tasks Board / Item
1:1Fat Free CRM Tasks belong to a user and optionally to an Opportunity or Contact, with title, body, due date, category, and completion status. We migrate both open and completed Tasks as Items on a Tasks Board, using a Status Column for completion state and Date Columns for due dates. Task-Contact and Task-Opportunity associations migrate as Item Connections to preserve the original linkages.
Fat Free CRM
Campaign
monday CRM
Campaigns Board / Item
1:1Fat Free CRM Campaigns track name, status, budget, and target metrics. We create a Campaigns Board with Columns for those fields. Campaign-Contact memberships (tag subscriptions and campaign_contacts join table) migrate as Item Connections linking each Campaign Item to the relevant Contact Items, preserving the many-to-many relationship.
Fat Free CRM
Tag
monday CRM
Label / Tag Column
lossyFat Free CRM uses the acts_as_taggable gem to store global tags across Contacts, Accounts, Opportunities, and Leads. Since Monday.com CRM has no native global tagging across boards, we either map tags to Monday.com Labels (on the respective boards) or create a Tags Board with Items representing each tag, linked back to their source records via Item Connections. The customer chooses the strategy during scoping.
Fat Free CRM
Custom Field
monday CRM
Custom Column
lossyFat Free CRM custom fields on Accounts, Contacts, Leads, and Opportunities are stored in extension tables or serialized fields. We extract the field definitions and values, then create matching custom Columns in Monday.com with the appropriate type (text, number, date, dropdown, checkbox). Dropdown options migrate as Status Column values. We cannot migrate formula-based custom fields from Fat Free CRM; these require manual recreation as Monday.com formula columns.
Fat Free CRM
Attachment
monday CRM
File (documented for manual copy)
1:1Fat Free CRM stores uploaded files on the host filesystem or a configured S3 bucket, not in the database. We enumerate every attachment record (filename, path, associated record ID, record type) and deliver a file inventory CSV. The customer copies binary files to Monday.com storage manually post-migration and reattaches them to the corresponding Items. We cannot extract binary file content through the standard database connection.
Fat Free CRM
User
monday CRM
Team Member
lossyFat Free CRM Users have login credentials, role (admin or user), and team membership. We extract the full user roster (name, email, role, team) as a reference table. Monday.com Team Members are provisioned by the customer's admin in workspace settings; we cannot create them without write access to the destination. The admin creates Monday.com accounts and we provide the mapping to reassign record ownership after migration.

Gotchas + challenges
Platform-specific issues from each side, plus the pair-specific challenges that don't show up on either platform's page on its own.
Fat Free CRM gotchas
No public REST API forces direct database extraction
Plugin-extended schema may alter core tables
Attachment files live on the host filesystem
Users and groups must be manually remapped in the destination
monday CRM gotchas
Subitems are not included in bulk exports
Daily API call limits vary sharply by plan
Legacy automations (Sentence Builder) are being deprecated
Excel and account exports only include table views
Enterprise admins can disable non-admin exports
Pair-specific challenges
Migration approach
Database discovery and schema inventory
We connect read-only to the Fat Free CRM database (MySQL, PostgreSQL, or SQLite as confirmed during scoping) and run a full schema discovery pass. We enumerate all tables, columns, join tables, plugin-added columns, and custom field definitions. We also count records per object (Accounts, Contacts, Leads, Opportunities, Tasks, Campaigns), enumerate attachment paths, and export the user and group rosters. This inventory drives the migration scope document and identifies any plugin-extended schema requiring additional mapping work.
Monday.com board and column design
We create the destination Boards in Monday.com (Companies, People, Leads, Deals, Tasks, Campaigns) with typed Columns matching the Fat Free CRM field inventory. We configure Status Columns for stage/status values, Date Columns for due dates and close dates, Number Columns for amounts and probabilities, and Dropdown or Labels Columns for picklist fields. For custom fields discovered during schema review, we create matching custom Columns. Item Connections are provisioned on Deals and Campaigns boards to receive the opportunity-contact and campaign-contact relationship data.
Test migration in a staging Monday.com workspace
We run a full migration into a staging Monday.com workspace using production-like data volumes. The customer spot-checks 25-50 randomly selected Items across each Board against the Fat Free CRM source records for field accuracy, relationship integrity, and attachment reference completeness. Any mapping corrections (wrong column type, missed custom field, relationship direction error) are documented and corrected before the production migration begins. Attachment file inventory is validated against the filesystem.
User and group roster handoff
We deliver the full user and group roster as a structured reference table. The customer's Monday.com admin creates Team Members in workspace settings, assigns appropriate workspace roles (member, viewer, admin), and maps each Fat Free CRM user to a Monday.com Team Member by email. We cannot provision Monday.com users without destination write access; this step requires admin action and is a gate for production migration.
Production migration in dependency order
We run production migration in record-dependency order: first Companies (Accounts), then People (Contacts) with Account connections resolved, then Leads, then Deals with Contact connections resolved, then Tasks, then Campaigns with Contact connections resolved. Tags migrate as Labels on each Board or as a Tags Board depending on the customer's chosen strategy. Custom fields migrate as custom Columns. Each phase emits a row-count reconciliation report before the next phase begins.
Cutover, attachment recovery, and automation handoff
We freeze Fat Free CRM writes during the cutover window, run a final delta migration for any records modified during the window, then confirm Monday.com as the system of record. We deliver the complete attachment file inventory CSV with source paths and linked Item IDs. The customer's team copies files to Monday.com and reattaches them. We deliver a written automation inventory documenting every Fat Free CRM plugin-based workflow with a recommended Monday.com Automation equivalent for the customer's admin to rebuild.
